Returns an array containing the specified object as first element follows by its transitive closure. The closure of an object are all objects that can be reached by indirect references. The transitive closure is the result of applying the calculation of the closure to a closure as long as no new objects came along. This is e.g. useful for getting all objects belonging to the resources of a page.
